The extraordinary turnout is just as big a part of the Minnesota story. Consider this: Clinton racked up more votes than people who caucused as Democrats in 2004, and she finished a distant second.

Democrats were on course for turnout above 200,000, nearly four times as high as the last presidential year. Republicans came out in smaller numbers, but still set a record for the party. With more votes still to be tallied, the GOP's turnout topped 60,000.
